for sure: improper setting of 6° and maybe phase setup can for sure render the heli to hard-to-impossible to fly
Gain/sensetivity problems, GT
as far as i know - as said: no personal experience with 4 heads - there are different kinds of multi-head setups (some needing cyclic phase setup, some not) depending on servo positioning and swash/head geometry. best could be to make a photo of your head/swash from above - so that head/swash/servo geometry can be seen. then Tomas or some of the scale guys will for sure be able to give the right advice

My 4blade head has a standard 3 servo setup as you will ser on any trex.. but i didnt do any cyclic phasing. Its at O..
When i tried 45degree everything var 45degree off. Trying to go straight, it goes 45degre right front.. and so on.

In my opinion with the 2 blades you have a cyclic delay with the 4 blades you have another delay cyclic.
But ask zex understand more.
Is easy tilt the plate and measure the degrees on the model with 2 blades.
After titl the plate and measure degrees on the model with 4 blades.
You will see that they will be different.
I'm not English it's hard for me to explain it in words.
But I think they need a number lower than 90 degrees.
But listen to zex that he created the spirit

Let's see if I can explain myself.
In this image there is a 2-blade model, when you tilt the swashplate aileron to the right ; when the linkage called 1 it is in that position thanks to the length of the yellow lines you have an angled blade when it is found on the nose of the helicopter.
while your 4 blade when linkage 1 is on the same point, thanks to the yellow lines with different length you will have the blade inclined in a different position and not when it's on the nose helicopter.
I've been clear?

Rdlx3m you know what i mean?
With a helicopter at 2 blades has a cyclic command after 90 degrees.
While your helicopter with 4 blades you have a cyclic command after 45 degrees.
Tell me if you understand?
Have you tried entering 45 degrees in cyclic phase?
Now I don't know if -45 or + 45

Cyclyc phase is at -0-. Thats correct setting, 6degree tuning is i believe correct if you see pics. I lowered cyclic speed. Helped alot. But heli still wiggles around the whole area. Really hard to hover in one place

listen me please
0 it's right for models with 2 blades but with the 4 blades it's wrong.
reset any changes you made
set cyclic phase 10 and try.
if that's not enough set cyclic phase 20.
i set helicopter EVERY DAY all my friends they come to me to set up their helicopters.
I have just one doubt is is 10 or -10
listen to me carefully
move the radio stick of the aileron To the right
and now the highest point of the swashplate is indicated by the red line
we moving parameter cyclic phase we have to make sure that the highest point of the swashplate be moved on the blue line (in the direction of the yellow arrow)
that's all
it's easy
we have to move the position of the cyclic, start with 10 and if needed we get to 20.
you just have to understand if set 10 or -10
only this parameter and your helicopter it will fly well.
but reset all the changes you made otherwise they may interfere.
